Looking for "package type, pin configuration, terminal names, how many source/drain pins, gate pin, footprint/package designation for SiSS52DN-T1-GE3" in siss52dn.pdf

Identifying metadata issues.

I reviewed the current part project against the available project data and the existing datasheet workflow for part verification. The right process here is: confirm the Datasheet URL, extract metadata + pin data from the datasheet, then compare that against the terminal elements and footprint pad map in the part project
Status
  • Datasheet property: already set to the official Vishay PDF, so I did not change it.
  • Project type: this is a part project with terminal elements already created.
  • What I could verify directly from the project: MPN, manufacturer, description, terminal count, terminal names, terminal numbers, and footprint pad count.
  • What remains limited: the datasheet/PDF extraction tools timed out, so I could only cross-check against the project plus official/distributor metadata visible from search results, not a full parsed pin-function table.

Current part metadata

FieldCurrent valueAssessment
Manufacturer Part NumberSiSS52DN-T1-GE3Looks correct
Manufacturer NameVishayLooks correct
Part TypeTransistorsBroad but acceptable; MOSFET would be more precise
Designator PrefixQCorrect
DescriptionN-Channel 30 V (D-S) MOSFETCorrect but minimal
Datasheet URLhttps://www.vishay.com/docs/79977/siss52dn.pdfAlready set, official
Package / Case CodeMissingShould be added
Key specs I could confirm
From the official Vishay search result and exact-MPN distributor listings:
  • N-channel MOSFET
  • 30 V drain-source rating
  • Package family: PowerPAK 1212-8S / 1212-8SH
  • Distributor listings for this exact MPN show 8-pin package family, surface mount, and headline current ratings around 47.1 A (Ta) / 162 A (Tc)
Symbol / terminal audit
The schematic currently has 11 terminal components, which is consistent with a MOSFET package model where multiple drain/source pads are broken out individually in the part project for footprint mapping. The terminals present are:

D_610DrainUnspecifiedLabel looks plausible, type missing
D_711DrainUnspecifiedLabel looks plausible, type missing
Footprint audit
The layout contains:
  • 11 pads
  • one footprint container
  • fab/silk primitives and text
  • pad designators matching the 11 terminal labels above
So the symbol terminal count and footprint pad count are internally consistent.

Mismatches / issues flagged

IssueSeverityNotes
Package or Case Code missingMediumShould be populated with the exact datasheet package string
All terminal Pin Type properties are UnspecifiedMediumFor a MOSFET part, these should be typed at least as Gate/Input-like and Source/Drain passive or appropriate project convention
No Pin Description properties visibleLowHelpful for library quality, though not strictly required
Description is minimalLowCould be improved with package + key rating
Part Type is generic (Transistors)LowMOSFET would be more searchable/precise
Bottom line
  • No obvious symbol-to-footprint mismatch: the project has 11 terminals and 11 footprint pads, and the naming pattern is sensible for a MOSFET with one gate, multiple source pads, and multiple drain pads.
  • Main quality gap: metadata completeness and terminal property completeness, not gross pin-map inconsistency.
  • Most likely needed updates:
    • add Package or Case Code
    • set terminal Pin Type
    • optionally add Pin Description
    • optionally tighten Part Type and description
If you want, I can do the cleanup pass next:
  • fill in the missing package property
  • set pin types for all 11 terminals
  • add short pin descriptions
  • update the description to a cleaner library-style summary
The only thing I’d still want to confirm before editing is the exact package string from the datasheet page itself, since the PDF extraction timed out in this run.
